Dear List members,
thanks for your comments. It is my opinion that all anaerobes extract
oxygen from their substrate. Therefore, I feel that in addition to
digestibility, the oxygen content of the substrate is also an
important factor.In fact, the two go hand in hand. A substance devoid
of oxygen cannot be digested (e.g. plastic, petroleum)
